Replacement Filter Carridges Medium-6 Pack 09830

great buy! will keep purchasing these for our turtles....only have to clean the take once a month or even longer if i clean the filter in between cleanings!

I got exactly what was stated medium 6-pack and the delivery time was great. Happy!!!!

They work fine

Turtle cage

Use these in my tank with 4 turtles and they definitely do their job. I do have to change them rather frequently, every 2 weeks or so but there are 4 turtles and they are messy. Ive purchased these at the pet store for much more, this is definitely the best value.

We love these for keeping our turtle tank clean.

The Zilla Water Filter itself is really good. They claim the cartridges last a month, but thats not been my experience. I replace them weekly, and I keep the tank clean. But overall its a good buy.

My turtle tank had gotten extremely gunky from having over fed them one time. I hate cleaning it out and I had just done a full clean of the tank recently. I replaced the filter cartridge a couple days after realizing it was still dirty. Within hours my tank water was almost clear! Love it.

I use this for my 20 gallon turtle tank, works very well, great price for the 2 pack this size is hard to find.

My only complaint is that they dont seem to last as long as I thought they would. I do rinse them out one or two times but really they probably last 1 - 2 weeks max. Maybe that is okay though because it means they are filtering the water well.
